This invention relates to a material cleaning device and particularly tomeans adapted to prevent clogging of the discharge passage of such adevice.

In one form, this invention is applied to a hydro-separator adapted toseparate coal from other material. Many of the impurities present withthe coal are heavier than the coal and the mechanism to which myinvention may be applied embodies means for subj ecting the coal andrefuse to a powerful upward current of water. The coal is raised andcarried off over a partition and the refuse, by reason of its greaterweight, passes downwardly and is discharged through an opening. Theopening is controlled by means of a gate which may be lowered to closethe opening entirely and may be adjusted to vary the size of theopening. It is one of the objects i. of myinvention to provide means foracting upon the gate to prevent clogging of the refuse at the dischargeopening which is controlled by the said gate. Other objects appear fromtime to time in the specification and claims.

The invention is illustrated in the accompanying drawing, which is afragmentary vertical cross section, showing a hydro-separator with mygate installed and with parts omitted.

A indicates a chamber into which coal A is delivered by means of a chuteA The chamber A is formed by suitable walls and is generally watertight. A partition A is provided with an opening A at its bottom. A

gate A 1s provided to control the opening A. It may be moved to close itentirely or to vary the size of the opening. A is a controlling rod bymeans of which the'gate is raised and lowered. The rod is threaded atits upper end as at A and is provided with a wheel A A is a support forthe rod A A is a screen which forms the bottom of the chamber A.

B is a water chamber located beneath the chamber A and separated from itmainly by the screen A. B is a nozzle projecting into the chamber B bymeans of which a current of water may be discharged into the chamber B.The movement of the current of water is indicated by arrows,particularly in chambers A and B. V

C*G are particles of coal moving upwardly in the current of water afterthey have been separated from the refuse D which is shown as movingdownwardly along the screen A toward the discharge opening A. Eds. achute, onto which the coal is dis charged as it passes from the chamberA over thepartition A It may be removed and dewatered in any suitablemanner.

FjlS a rotating shaft provided with acam member F positioned on it andadapted to rotate with it. F is the cam part formed on the, member F Gis a lcversupported for movement at G in a member G? which may bemounted on the framework of the hydro-separator or may be supported inanyother suitable manner. Ashindicated in the drawings one end of theleverG contactsthe hand wheel A and the other is periodically depressedby the cam F 1 It will be evident that while I have shown in my drawingan operative device, still many changes mightbe made in the size, shape,arrangement and disposition of parts, without departing from the spiritof my invention.

In particular, the mechanism for giving the gate its reciprocatory orvibratory movement might be widely changed and the direction, amount andnature of the movement given tothe gate to prevent clogging might bealmost infinitely changed without departing from the spirit of myinvention.

When in this specification and in the claims the expression vibratory orreciprocatory movement is used, I mean in general a shaking action;ordinarily a motion of the type shown would be satisfactory and asshown, of course,

it is a regular reciprocatory movement. An irregular movement mlght beused and for the purposes of the invention almost any jarring or shakingmovement might be satisfactory. v I I The use and operation of theinventlon are .as follows: V

With the parts in the positions shown, a

combined stream of coal and refuse is discharged into the chamber A,which is filled with water.. The water is circulated by dis chargingthrough the nozzle B and passing over the partition A As the stream ofcoal and refuse passes into this upwardly moving current of water thegreater part of the coal follows the upwardly rising current, isseparated from the refuseand passes over the partition and is collectedby means of the chute E or by any suitable mechanism. At the same timethe heavier refuse resists the effect of the upwardly rising current ofwater, passes downwardly across the screen and is discharged from thechamber A and thereafter is collected and removed in any suitablemanner.

It has been found that for any one of many reasons clogging sometimestends to take place at the point of discharge of the refuse from thechamber A. I have discovered that if the gate which controls the size ofthe dis charge opening is given aslight vibratory movement, the tendencyfor clogging is greatly reduced. In the form of my invention shownherewith I have, therefore, provided means for reciprocating the gatevery slightly in a more or less vertical path. The gate is thus raisedand lowered constantly. The amount of the movement is slight, in somecases not more than inch and in some cases even less. The lever actionillustrated causes this reciprocatory movement. In apparatuses of thissort it is practically certain that there will be a rotating shaft andit is generally convenient to mount the cam on such a shaft. The levermay then be positioned so as to be periodically depressed by the cam andwith each depression of the lever at one end its opposite end is raisedand in the form shown herewith the lever thus contacts the hand wheel onthe gate shaft and raises it. As soon as the cam has passed out ofengagement with the lever, the gate is free to drop and does so, raisingthe lever at one end while depressing it at the other, and thisalternate raising and lowering of the gate will take place as long asthe parts are in motion.

I claim:

1. In combination in a hydraulic separator having a stationaryseparating chamber, means for supplying mixed materials to said chamberand means for forcing a current of water through said chamber, saidchamber provided with a discharge for the refuse'and a discharge for thecleaned material, a gate member adapted to control the discharge ofrefuse, axially movable adjustment members for said gate to vary thesize of the discharge opening including a handle, and means engagingsaid handle and operable to impart vibratory movement of said gate.

2. In combination in a hydraulic separator having a separating chamber,means for supplying mixed materials to said chamber and means forforcing a current of water through said chamber, said chamber beingprovided with a discharge for refuse and a discharge EARL STUlSIP.
